Before Infrared Images from the Rockland Public Library
Infrared analysis allows us to see temperature differences by measuring the infrared radiation each object emits. Warmer objects emit more infrared radiation and appear yellow; cooler objects appear pink to purple to even black. The Rockland Public Library‘s beautiful architecture looks pretty amazing through the infrared camera, though it’ll be much more comfortable and efficient once we’re done. Check back for the After images!
The Reading Room is a beautiful space, with an imposing fireplace and elegant arched windows. But look how cold the chimney, windows, and arch are! Insulation deficits are largely to blame, but our production crew found also huge gaps between the trim and the wall.
Though it was nestled inside the attic, the Library’s central dome was essentially exposed to outside air temperatures. The infrared picture makes that clear!
This wooden eagle hangs above the Library’s Quiet Room. Hand-carved it 1865, it lived in the Custom House on Rockland’s Main Street for many years before perching here. The infrared image shows how well wood holds heat, especially compared to the cold wall cavities behind it.
Why are those walls so cold? A look from behind explains everything: there is absolutely nothing behind the plaster. A dumbwaiter travels from this attic, behind the Quiet Room, and down into the Library’s basement, providing a highway for cold air.
